Mathematical Modeling of the Extraction Process Essential Oils Schinus terebinthifolius Raddi Using Supercritical Fluids

Schinus terebinthifolius Raddi is a plant rich in nutrients and is used medicinally and industrially. Supercritical oil extraction from S. terebinthifolius can result in higher value-added products. Mathematical models (Sovova and Esquivel) are used to describe the behavior of supercritical extractions. This study aims to compare both models in terms of yields in conditions of 223 bar and 50°C. We observed that the model proposed by Sovova provided good reproducibility and representativeness.
